Subject: Chemicals put in alcohol before transport to deter thievery???

Quite a few years ago (maybe 15 years) someone told me that 
alcohol manufacturers put a certain chemical in tanker trucks 
transporting their product to the bottling plants. Before 
bottling, an antedote was poured into the alcohol to counteract 
the poisoning to someone from this chemical. This was done to 
deter any truck high-jacks of the product. I believe this is no 
longer done, however I would like to know the chemical which was 
used at that time, for this purpose.

Thank you, you have a great site!
